If I execute the app in a device with version 4.4.2, no exception is thrown, but executing the app on a device with lower version, the app crashes..

The reason is clear:
12-05 11:34:50.716: E/AndroidRuntime(327): Caused by: java.lang.OutOfMemoryError: bitmap size exceeds VM budget
Solution: try to use the drawable with smaller resolution.

You have run out of memory which caused a bunch of issues (cannot inflate the activity xml which causes the activity to not start since you get an exception in the onCreate method that is not handled)

to fix it try loading a smaller size bitmap for in your imageview for lesser devices (pre 4.4.2)

App crashes in 2.2 but not in higher versions

I am using appcompat_v7 for actionbar compatability & android-support-v4.jar for fragment compatability, but my app crashes in 2.2.

You are calling methods that does not exist in Android 2.2 (but do exist in later versions). Use Lint tool to check your code and fix it.

Android: Error when using QRGen lib to generate QR code

I am trying to generate QRCode image using QRGen library.
I have imported qrgen-1.0.jar file to my project.
I know this question is duplicate.
I have referred following code by this link
public Bitmap qrBitmapFromString(String qrText){
ByteArrayOutputStream out = QRCode.from(qrText).to(ImageType.PNG).withSize(300, 300).stream();
byte[] data = out.toByteArray();
Bitmap bmp = BitmapFactory.decodeByteArray (data,0,data.length, null);
return bmp;
}
But I am getting the following error.

2.0-SNAPSHOT should solve this https://oss.sonatype.org/content/repositories/snapshots/net/glxn/qrgen/android/2.0-SNAPSHOT/
https://github.com/kenglxn/QRGen

Finally I found and following thing working well for me.
Right click on your project
Go into Build Path
Configure Build Path
Go to Order and Export
Check your OnBarcode library
Clean your project
Think this may help some one like me.
Thanks.

error log says
Could not find class: fragment
Fragments require API Level 11 or greater :)
If you want to use Fragments on API < 11 you need to use Support Library package for this.

Looks like this was fixed in HoloEverywhere 1.4.1: https://github.com/ChristopheVersieux/HoloEverywhere/issues/
Did updating to 1.4.1 fix the problem for you?

Try to add your fragment programmatically.
That is, your xml should have only the layout 'content' and, onCreate:
if (savedInstanceState == null) {
// Add the fragment on initial activity setup
MyFragment myFragment = new MyFragment();
getSupportFragmentManager().beginTransaction().
add(R.id.content, myFragment).commit();
}

I am a absolute beginner to phonegap and sencha touch. After reading many forums I got this plugin for eclipse : http://www.mobiledevelopersolutions.com/home/start/startdetails
But, when I am trying to run the project with google api 2.1 with minsdk version 7, I am getting the error mentioned above. Any ideas how to recitfy it?

I received a report of what is likely the same issue today and tracked it down. See AppLaud Issue #63.
The Sencha file structure changes in 2.0.0-pr4 cause the AppLaud wizard to fail to complete project creation. plugins.xml is missing and AndroidManifest.xml is not set up.
The workaround is to copy sencha-touch-all-debug-w-comments.js to sencha-touch-debug-w-comments.js and then the wizard will succeed with project completion.
This bug will be fixed in the next AppLaud update due out after the PhoneGap 1.4.0 release.
Also, note that the bundled Sencha PhoneGap example in AppLaud does not yet support the Sencha 2 APIs. See AppLaud Issue #64.

Looks like you are missing the res/xml/plugins.xml file from your project.
